## Detailed Description

### template<class SEQUENCE>
class vigra::SequenceAccessor< SEQUENCE >

Accessor for items that are STL compatible sequences.

It encapsulates access to the sequences' begin() and end() functions.

Usage:

#include <vigra/accessor.hxx>
Namespace: vigra

        typedef std::list<std::list<int> > ListOfLists;

        ListOfLists ll;
        ...

        typedef vigra::SequenceAccessor<ListOfLists::value_type> ListOfListsAccessor;
        ListOfListsAccessor a;
        for(ListOfLists::iterator li = ll.begin(); li != ll.end(); ++li)
        {
            for(ListOfListsAccessor::iterator i = a.begin(li); i != a.end(li); ++i)
            {
                *i = 10;
            }
        }

## Member Typedef Documentation

typedef SEQUENCE::value_type component_type

the sequence's value_type

Reimplemented in VectorAccessor, RGBAccessor, and VectorAccessor< RGBVALUE >.
